Genetic Link to CPPD
EurekAlert!
In a first-of-its-kind genome-wide association study (GWAS) researchers have discovered two genes, RNF144B and ENPP1, that cause calcium pyrophosphate deposition (CPPD) disease in Americans of European and African descent.

Genetic Sequencing in Rheumatology
Genetic sequencing as a research and diagnostic tool has expanded in medicine and rheumatology. An interesting review in Arthritis and Rheumatology suggests that despite currently modest use, there will be an expanded role for genetic sequencing in the field of rheumatology.

Lupus in an empty house
The full house immunofluorescence pattern is the classic histopathologic finding of lupus and lupus nephritis. Glomerular deposits staining for IgG, IgA, IgM, C3 and C1q can help confirm a suspected diagnosis of systemic lupus erythematosus (SLE). This https://t.co/Zcywc5r9q9

>200 genes 🧬 implicated in #SLE
Complex indeed!
And
▶️ 7 clusters of signalling pathways
So we have to have many Rx options
Ab patterns vary
LN flares can have v diff pathways between Pts

The ANA pattern I hate
#DFS
Why
Dense fine speckled should R/O #SLE
But mimicking patterns that MAY Have #lupus
AC-2 pattern mimickers ex AC-4
Machine learning models to help
▶️improved accuracy

Who with +ANA will become #SLE
Mostly similar cytokine signature
But ⬆️IFN and
more innate immune changes
👇
In those who developed #lupus
? prediction & Prevention model in +#ANA people 🤷♀️

Who does worse with #SLE
#nature vs #nurture
South American #lupus #registries
⬆️ activity

A brief history of familial Mediterranean fever - FMF is most common periodic fever syndr. an inherited polyserositis mainly affects Arabs, Armenians, Jews, & Turks.

Single center study of 2741 ANA tests: 65% ANA negative, 31% ANA+ w/ nuclear staining patterns, & 2.0% ANA+ w cytoplasmic staining. Cytoplasmic - most were reticular, dense fine speckled next. Reticular assoc w/ primary biliary cholangitis (w/ Abs against M2). Dense fine https://t.co/JI7iGvw8xp
